There was a rash of these a few years back. If you looked at the surroundings some 10 or so "different" trucks were at exactly the same place, in front of the same brick wall, with wheels in exactly the same place in rotation, the same tractor (with no legible ID and the same color), same clouds in the same position - it was all one picture photo-shopped.
FedEx would never allow use of their logo on a non-company-owned truck, in fact if they find this fake and are able to run down who did it they will prosecute.
